[jira] [Commented] (SPARK-7155) SparkContext's newAPIHadoopFile
does not support comma-separated list of files, but the other API

> Key: SPARK-7155
> URL: https://issues.apache.org/jira/browse/SPARK-7155
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 1.3.1
> Environment: Ubuntu 14.04
> Reporter: Yong Tang
>
> SparkContext's newAPIHadoopFile() does not support comma-separated list of files. For example, the following:
> sc.newAPIHadoopFile("/root/file1.txt,/root/file2.txt", classOf[TextInputFormat], classOf[LongWritable], classOf[Text])
> will throw
> org.apache.hadoop.mapreduce.lib.input.InvalidInputException: Input path does not exist: file:/root/file1.txt,/root/file2.txt
> However, the other API hadoopFile() is able to process comma-separated list of files correctly.
> In addition, since sc.textFile() uses hadoopFile(), it is also able to process comma-separated list of files correctly.
> The problem is that newAPIHadoopFile() use addInputPath() to add the file path into NewHadoopRDD. See Ln 928-931, master branch:
> val job = new NewHadoopJob(conf)
> NewFileInputFormat.addInputPath(job, new Path(path))
> val updatedConf = job.getConfiguration
> new NewHadoopRDD(this, fClass, kClass, vClass, updatedConf).setName(path)
> Change addInputPath(job, new Path(path)) to addInputPaths(job, path) will resolve this issue.
